How does 2 Corinthians 6:18 define the relationship between God and believers? Text “ ‘I will be a Father to you, and you will be My sons and daughters,’ says the Lord Almighty.” — 2 Corinthians 6:18 Immediate Setting in the Letter Paul has just commanded the Corinthian believers, “Do not be unequally yoked with unbelievers” (6:14) and “come out from among them and be separate” (6:17). Verse 18 crowns that call to holiness with the climactic promise of filial relationship: separation from idolatry is not an end in itself but a prerequisite for intimate communion with God. Old Testament Roots and Covenant Continuity Paul fuses several covenant texts: • 2 Samuel 7:14 — “I will be his Father, and he will be My son.” • Isaiah 52:11 — “Depart, depart, go out from there! Touch no unclean thing.” • Jeremiah 31:9 — “I am Israel’s Father.” By weaving these strands, Paul shows that the Father–child motif, first spoken to Israel and the Davidic king, now embraces all who are in Christ. The God who formed the nation now forms a family from every nation (cf. Revelation 5:9-10). Doctrine of Adoption Romans 8:15-17 and Galatians 4:4-7 parallel this text: believers receive “the Spirit of adoption crying, ‘Abba, Father.’ ” Legally in first-century Corinth, adoption (huiothesia) granted an heir every right enjoyed by a biological child. Paul borrows this juridical reality to assure Christians that the Father’s commitment is irrevocable. Regeneration and Indwelling The promised Fatherhood presupposes new birth (John 3:3; 1 John 5:1). The Spirit unites believers to the risen Christ, making the family bond experiential, not merely forensic (2 Corinthians 13:5). Thus 6:18 is inseparable from 6:16: “We are the temple of the living God.” Holiness and Separation Because God’s paternity is holy, His children must break partnership with pagan worship (1 Corinthians 10:14-22). Excavations at ancient Corinth (e.g., Temple of Aphrodite, Asklepion healing cult) demonstrate the pervasiveness of idolatry that threatened the church’s purity. Paul’s command therefore addressed concrete pressures, not abstract theory. Privileges Flowing from Divine Fatherhood 1. Access in prayer: “If you then, being evil, know how to give good gifts… how much more your Father” (Matthew 7:11). 2. Protection: “No one can snatch them out of My Father’s hand” (John 10:29). 3. Discipline: “The Lord disciplines the one He loves” (Hebrews 12:6-10). 4. Inheritance: “Heirs of God and co-heirs with Christ” (Romans 8:17). 5. Future glorification: “We know that when Christ appears, we shall be like Him” (1 John 3:2). Responsibilities of Children • Moral purity (1 John 3:3). • Love for the family (John 13:34-35). • Evangelistic witness (Philippians 2:15). • Reverent fear (1 Peter 1:17). Corporate Dimension Paul says “sons and daughters,” plural. The relationship is simultaneously personal and communal, binding believers into a trans-ethnic household (Ephesians 2:19). This demolishes social barriers endemic to Roman society—slave/free, Jew/Gentile, male/female—anticipating the eschatological community of Revelation 21:3. Summary 2 Corinthians 6:18 defines the believer’s relationship to God as an unbreakable, covenantal Father–child bond. Rooted in Old Testament promise, ratified by Christ’s resurrection, assured by the Spirit’s indwelling, and evidenced by transformed lives, this filial connection grants both privilege and responsibility. It calls believers to purity, unity, and confident hope while showcasing the loving character of the Lord Almighty who adopts sinners into His eternal family. |
